Self-study Programme 513
The Golf 2013
The new Golf
The Golf 2013 is the first vehicle to be launched by
the Volkswagen brand which is based on a new
concept used for all platforms, the “Modular
Transverse Matrix” (MQB). Many of the mechanical
units, subassemblies and systems have been
completely re-developed within the scope of the
MQB.
This makes the seventh generation of the Golf a
completely new release, and one which is
accompanied by many innovations. The Golf 2013
sets new standards in its vehicle class when it comes
to convenience, quality and safety features, as well as
the assistance systems available for the vehicle.
This Self-study Programme will provide an overview
of the design and function of the new Golf and help
explain many of the technical innovations it boasts.
The individual chapters contain references to further
Self-study Programmes which provide more detailed
information on the way the individual vehicle
components are designed and constructed.

Introduction
The Modular Transverse Matrix (MQB)
The modular transverse matrix, or MQB for short, is the new modular strategy introduced by the Volkswagen
Group. Under the direction of the Volkswagen brand, this modular transverse matrix will be launched for the
Volkswagen, Audi, SKODA and SEAT brands. The models Polo, Beetle, Scirocco, Jetta, Tiguan, Touran, Sharan,
Passat, Volkswagen CC and, as the first vehicle model of them all, the Golf 2013 are being assembled using the
MQB as a basis.
Vehicle architecture
The integral feature of the modular transverse matrix
is a flexible vehicle architecture. This has been
divided into five principle vehicle sections. The central
dimension is the area between the pedal cluster and
wheel centre.
This dimension is uniform in all vehicles and is based
on a standard engine installation position which is
transverse to the direction of travel. Other dimensions
which characterise the concept, such as wheelbases,
track widths, wheel sizes and seat positions, have
been standardised across the Group while remaining
variable.

Module families
The modular strategy characterising the MQB is based on the following standardised module families:
• Electrics/electronics
• Drive
• Running gear
• Vehicle design (vehicle body, air conditioning system, seat system, airbags)

Since the early 1990s, a number of
different models have been produced on
a shared platform.
This strategy involves dividing the vehicle
into the body-in-white and the platform.
The technical features of the platform
components are virtually identical.

In the year 2000, this strategy was
supplemented with the launch of the
module strategy. Modules with basic
technical functions and designs which
are identical were introduced to a
variety of vehicles.

Since 2007, the use of modules has been
extended to the entire vehicle, and has
been introduced across all vehicle
classes as well. From 2012 on, the same
modules will be used across the entire
Group within the modular strategy.
Standardisation across all brands
Some of the advantages provided by standardisation across all brands include:
•
•
•
•
VW production will become faster, simpler, more cost-effective and more flexible through standardisation
across the brands. It will simplify development, creating synergies right across all brands and vehicle series.
The modular matrix strategy will allow the number of versions, and their complexity, to be reduced significantly.
Standardised production processes are made possible by employing uniform joining sequences in body
construction, a uniform assembly sequence and uniform installation concepts.
It is now possible to produce models based on the MQB architecture, even when they are made by different
brands, together on one and the same production line.
